New to all of this. Here's my data.
Recently had a home sleep study done.  Dr. said I had "severe" apnea.
Results of the test and my first night of data: h ttps://imgur.com/a/RMHBo (space in link since this is my first post)
I'm wondering what you guys think about this, even though it has only been one night so far.

RE: New to all of this. Here's my data.
Welcome TM76.  The good news is you got tested and found your severe apnea...the bad news is you have mixed central and obstructive apnea and you need an Adaptive Servo Ventilator (ASV) type of machine.  CPAP will not treat your problem, and I'm not event going to try to give you pressure suggestions to lower this high central event rate. Note, your obstructive apnea is almost completely treated here, but the CPAP is not intended to treat central apnea and hypopnea.

What is going to happen is you need to do your best to use the machine, but start reading about mixed apnea and ASV.  You will probably fail to achieve good treatment results with CPAP, and you need to let your doctor know as soon as possible.  Your sleep test results have all the necessary information to change your diagnosis from obstructive to mixed and central apnea.  Insurance will require you to fail at CPAP to qualify for the machine you need.  You and your doctor need to work together to schedule a titration test to evaluate BiPAP and BiPAP-ASV.  Once you get the ASV, your rate will likely drop to less than 2 events per hour, and most likely less than 1 event per hour.  In some relatively rare cases, the central events do settle down and improve with CPAP so you will likely be required to try this therapy for a month, but you can let your doctor know of your progress before then so things move faster.

We are here to help you and coach you through this difficult bureaucratic process.  Many members here have that experience already.  Be patient, and be prepared to work harder at this than most, and it will work out in the end.  It may be frustrating and the biggest challenge is not to quit...get the treatment you need.

Wow.
I was hoping for a little better news than that, but this is life.
Thank you, Sleeprider, for you quick and informative response.
I will take your advice and talk to my doctor and research ASV machines.
If I see any changes in the meantime, I'll post updated data.

RE: New to all of this. Here's my data.
As I said, some people do achieve efficacy with CPAP, but your post was great in that you included the sleep study. That explains the CA events perfectly. I don't want to seem cynical, but I have coached and helped many individuals with results like yours, and it is rare for them to get consistently less than 8 events per hour on CPAP. I just thought I'd level with you that my expectations are low, but we're here to help.

I'm not a doctor, but if I was and saw results in a sleep study like yours, I would insist on a clinical titration on the basis that anyone with your CAI generally fails CPAP due to centrals. It just saves time and frustration to get it out of the way. Instead you have an auto CPAP machine set to default pressures of 4-20 cm and instructions to self titrate. You're going to need more help than that.

It has been nearly a week since I started now.  I think things are improving.  Here is the data from last night.

RE: New to all of this. Here's my data.
well isn't that a big difference. You have to be happy with that. I have no answer as to why, but gift horses and all that.
I would try your min on 9 and see if that helps to stop some H before they start.

For auto-cpap, from machine data or software. You can set the min pressure 1 or 2cm below 95%. Or clinicians commonly use the maximum or 95% pressure for fixed pressure CPAP, this can also be used for min pressure.

Thanks ajack.  I will give that a shot.

All events usually disappear at 9 cm.  The big obstructive and hypopnea episode at 02:30 looks positional. I figure your minimum pressure is at least 8.0, and you might benefit from a cervical collar to avoid chin tucking.  Leaks look good, turn off VS2 events for now.

I'd listen to sleeprider, I saw a chart where positional apnea was also raising CA, I'd keep this in mind as you go forward. Chin tucking, which obstructs the airway can be a big cause
